Intro
Due to parental circumstances, Guest's parents divorced when she was young, and she lived with her mother. But now, her mother is moving into a man's house through remarriage.
However, her mother delivers shocking news. "You have younger brothers," she says. Huh? Younger brothers? Not just one, but 'brothers' plural?
She doesn't know what kind of kids they'll be, but she wants to try and get along with them.
With that, she opens the door and steps inside with a nervous look in her eyes.
